Application led February 24,1920.` Serial No. 360,769.

with extremely simple means by which thev mop rolls can be readily applied and detached; to provide an improved and simplified arrangement by which adjust-able spring pressure is applied tothe pressure roll; to provide a simplified means for connecting t-he mop frame to the handle; to provide improved means onthe mop frame itself for holding the fabric of the mop while in use; to provide an improved form of wringing handle, and to provide an extremely simple arrangement by which a brush can be detachably applied to the mop frame.

Reference is to be had to the accompanying drawings, in which- Fig. 1 is a plan of a mop constructed in accordance with this invention;

Fig. 2 is a side view;

Fig. 3 is a sectional view of the mop roll;

Fig. 4 is an elevation showing the way of connecting the mop frame with the handle;

Fig. 5 is an edge view of the wringing handle; n

Fig. 6 is a detail view of the end of the frame; y

Fig. 7 is a side view of the frame showing the application of a brush in accordance with this invention; and

Fig. 8 is a plan of said brush.

The invention is shown as applied to a wooden handle 10, and the frame 11 of the mop as made of a single piece of wire, the two ends of which are connected with a sheetmetal collar 12 which is attached to the lower end of the handle.` The method of attachment of the wire fra-me is extremely simple and inexpensive. The collar 12 is Aof a general cylindrical form; but is provided with two opposite convex projections 13 on its outer wall forming two passages between their surfaces and the cylindrical surface of the handle. top of these projections are openings for .the horizontal top portion 14 of the handle and ifor the ends 15 of the wire. These ends are inserted in the collar and put rin place; then the handle is forced in between the two wires and a screw or rivet introduced at 16 to hold the collar to the handle. In this way, it will be seen thatthe wire of the frame coming out at right angles to the handle at two places, at the top and bottom; and .extending through passages, prevents movement of the frame with respect to the handle and also makes the frame itself rigid as its ends are so firmly held.

The frame in addition to the horizontal upper part 14, is provided with two longitudinal side members 17, each of which is providedV with a. screw thread 18. This At the bottom and screw thread isv rolled on preferably to,

project above the surface of the side members 17 and permit of the winged nut 19 being applied over the end` of the wire. This is a convenient featurein practice. These nuts hold the springs 2O which bear on sheet metal bearing members 21 provided with open bottomed slots 22 for receiving the shaft 23 of the pressure roller 24. These sheet metal bearing members are of the frame. Each has two identical arms spaced apart and spaced from the frame 17 to form the bearing slots 22.

ystamped out flat and doubledover the wire The side frame 17 is provided with anr ogee curve 25, the concave portion of which at the top comes directly under the shaft 23 and the convex projection of which assists in preventing the displacement of the shaft. To apply the roll, the bearing members 2l have to be pushed up and the shaft then inserted. Afterward the spring will hold it in place.

Below this curve, the side members are provided with a concave bend or depression at 27 furnishing a bearing for the shaft 28 of the fluted mop roll 29. It will be observed that ythe pressure roll 24 bears on the mop 30 which passes around the mop roll 29 and yieldingly holds the shaft 28 in its bearing depressions. -The frame is provided with a convex projection 3l which guards against the displacement of the shaft 28. The mop 30 may be of any desired kind and I have shown a well known endless type.

The frame 17 projects down below the bearing at 27 and is provided with a curve at 32 extending downwardly and forwardly. The ends of these two curved portions are connected by an integral wire cross bar 33 which in practice extends over the surface of the mop. It is preferably provided with teeth 311 which are designed to hold in the surface of the mop and prevent the action of the mop on a rough floor rolling the upper part of the mop over the lower part, and thus preventing the proper action of the device.

This part of the frame also is conveniently employed for another purpose, namely to hold a brush 36. This brush is shown as provided with a stationary metallic plate 37 secured on the top and extending longitudinally. The sheet metal of which `this blade is made is bent over along the front to form a loop at 38. This constitutes the forward boundary and the bar 33 being inserted in it, the action of pushing it will positively operate the brush. The plate 37 is made of a single piece of sheet metal and at the rear a latch 39 is supported from the base of the plate and elevated slightly. This acts to permit of the ready insertion of the bar 33. All that is necessary in order to insert it. is to push it in over this spring latch 39. The latter then holds it in place until it is depressed and the bar detached.

The mop itself is wrung out by rotating the mop roll 29. This is provided for as usual, by bending the end of the shaft 23 out at right angles to form a crank 40, but in the present instance. I have improved on the usual construction in this place by providing the end of this crank with a spring 4-1 on which bears a washer 42 having an oval perforation and providing a pivot stud 43 on which is pivoted a, rod 44 on which is a rotary handle 45. The spring bears at the bottoni on internal projections 47 pressed out from the wire. It will be seen simply by reference to Fig. 1, that the handle can beturned outwardly for operation as shown in dotted lines, and then turned inwardly when the mop is to be used, to avoid its engaging the furniture or woodwork. In F ig. 5 it is shown in a straight condition to illust-rate the joint, but it is to be understood that it is never intended to be left in this position in practice.

It is to be noted that the top portion 14 of the frame, is materially spaced from the nearest roll 24. This is to permit the operator, while holding the bottom of the handle, to extend the fingers through the frame on both sides of the handle, and thus hold the whole mop rmly. This is very important in wringing. The old styles of mops have been very unhandy and troublesome in this respect.

This mop is so constructed that the frame can be made of a single piece of wire, the pressure roll adjustably pressed against the mop roll, the latter turned in the usual way to wring the mop and yet this handle can be brought around into a position to avoid injury to furniture and wood-work. This roll 29 is fluted so that it will grip the mop better and carry it along with it even when the necessary seam is reached.

The method of connecting the wire frame to the handle is simple, convenient and inexpensive and yet strong and reliable, and in fact, it strengthens the whole frame. The particular method of mounting the rolls is also an improvement over the old way as far as I know it. The arrangement for using a brush in this frame is also very convenient and effective.

Although I have illustrated and described only a single form of the invention, I am aware of the fact that modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore, I do not wish to be limited to all the details of construction and combinations of parts herein shown and described, but what I do claim is l. A device of the character described, comprising a mop frame formed of a. single piece of wire and provided with a pair of opposite concave bends and convex projections adjacent thereto, both formed by curving the wire. the bends constituting bearings for a mop roll shaft, and the projections guarding against its displacement, a mop roll having a shaft carried in said bearings, a pressure roll` and springs coiled on the trame for yieldingly forcing the pressure roll toward the mop roll and toward the centers of the concave bends.

2. A device of the character described, comprising a wire mop side frame having two ogee curves, each comprising a concave bend and a projection, one bend constitutin a bearing for a mop roll shaft and the other receiving a pressure roll shaft, said wire passing upwardly therefrom yto form an upwardly extending portion substantially in alignment with said bearings, a spring thereon. means for adjusting the pressure of said spring, a bearingmember slidably mounted on said upwardly extending portion and having a downwardly opening slot in front of said frame over the pressure roll bearing, and a pressure roll having a shaft entering said slot, whereby the pressure roll is yieldingly forced toward said mop roll bearing.

3. device of the character described, comprising a mop frame consisting of a single piece of wire having on each side a bend constituting a bearing for a mop roll, a slidable bearing thereon for a pressure roll, a spring on said frame in position for applying pressure to said slidable bearing, 5 said frame having a screw thread above the bearing, the thread thereof being of larger i diameter than the Wire frame, and a Wing nut on the screw thread for adjusting the spring, said Wing nut being capable of passe lng over the Wire from its end. f
